I do not use paypal

Had Paypal up until 2012 or so.
Until my son got scammed out of $1800 for a Ford Supercharger set up he paid for ...but never recieved.
Paypal at the time did little to no investigation as far as im concerned, said seller never recieved payment?
Where did it go? My son worked all summer for that money.
Im sure Paypal has come along way since then, dealing with 3rd party hackers, etc.

I know it was a rare situation, but just my bad luck, I guess.
Personal check,Money order, or chase quickpay for me.
